HOT-WATER. ATTACHMENT FOR GAS-STOVES.

Specification of Letters Patent.

Patented Nov. 19, 1918.

Application filed January 22, 1917. Serial No. 143,720.

22/ all whom it may concern:

Be it known that I, AUGUs'r BLOMQUIST, a

former subject of the Czar of Russia, have declared my intention of becoming a citizen of the United States, a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Hot-WVater Attachments for Gas-Stoves, of which the following is a specification.

My invention relates to improvements in hot water attachments for gas stoves and has for its object the provision of an improved construction of this character, which is highly efficient in use.

The invention consists in the combinations and arrangement-s of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a top plan view of a gas stove burner equipped with an attachment, embodying my invention,

Fig. 2 is a section taken on line 2-2 of Fig. 1, and

Fig. 3 is a section taken on line 3-3 of Fig: 1.

The preferred form of construction as illustrated in the drawings comprises a gas burner consisting of an outer annular gas chamber 4 and an inner central circular gas chamber 5, the gas chamber 4 being provided in its top with two sets of burner openings 7 arranged in the form of concentric rings, and the chamber 5 being provided with a set of burner openings 8 arranged in the form of a ring. The gas chamber 4 is supplied with gas through a mixing passage or chamher 9 communicating with a gas supply pipe 10 through a valve 11, as indicated. A branch pipe 12 leads from the pipe 10 and is provided with branches 13, 14 and 15. The branch 13 leads to a passage opening in the outer ring of burner openings 7, the branch 14 leads to a passage opening in the inner ring of openings 7 and the branch 15 leads to a passage opening centrally in the ring of openings 8, said passages serving to preserve pilot lights for lighting the gas escaping through said burner openings when valve 11 is opened as will be readily understood.

An outer annular water heating chamber 16 is formed integrally on top of the burner outside of and surrounding the burner onenings. An intermediate annular water heating chamber 17 is formed integrally on top of the gas chamber 4 between the rings of burner openings 7 in the top thereof, and an inner annular water heating chamber 18 is arranged above and between the chambers 4 and 5, as shown. At one side the chambers 16, 17 and 18 are connected together by means of passages 19 and 20 and at the opposite side the chambers 17 and 18 are connected by means of a passage 21. At said opposite side-the chamber 17 is formed with an outlet passage or pipe 22, and the outer chamber 16 is provided with a depression 23 passing under the pipe 22 and provided with an inlet pipe or passage 24 for admitting water to said water chambers.

By this arrangement, it will be observed,

thatthe water passing through the device will first pass through the outer chamber 16 and be partially heated therein, said outer chamber alSO serving to partially confine the flame and heat from the outer ring of burner openings 7. The water passing through the outer chamber 16 then passes into the inner chambers 17 and 18 and is thoroughly and intensely heated therein, the flame and heat from the inner set of burner openings 7 passing between said chambers and the flame and heat from the central burner chamber 5 pass ing through the space inclosed by the chamber 18, thus efliciently and intensely heating the water in said chambers. The heated water is drawn through the passage 22, thus compelling a complete and eflicient circulation of the water through the device.

While I have illustrated and described the preferred form of construction for carrying my invention into eii'ect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not Wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A device of the class described comprising a burner consisting of an outer annular burner chamber having burner openings in the top thereof arranged in two annular rings, and an inner central circular burner chamber having burner openings in the top thereof arranged in the form of a ring; an annular water chamber formed on the top of said burner surrounding the same; a second annular water chamber formed on the top of said outer annular burner chamber between the rings of burner openings therein; an inner annular waterchamber located above and between said outer annular burner chamber and said inner central burner chamber; connections between said water chambers atone side; a connection between the inner and the intermediate water chambers at the opposite side; an outlet connection with said intermediate chamber at said opposite side; and an inlet connection with said outer annular water chamber at said opposite side, substantially as described.

A device of the class described comprising a burner consisting of an outer annular burner chamber having burner openings in the top thereof arranged in two annular rings, and an inner central circular burner chamber having burner openings in the top thereof arranged in the form of a ring; an annular water chamber formed on the top of said burner surroundingthe same; a sec- 0nd annular water chamber formed on the top of said outer annular burner chamber between the rings of burner openings therein; an inner annular water chamber located above and between said outer annular burner chamber and said inner central burner chamber; connections between said water chambers at one side; a connection between the inner and the intermediate water chambers at the opposite side; an outlet connection with said intermediate chamber at said opposite side; an inlet connection with said outer annular water chamber at said opposite side; a "alve and a pipe supplying to sa1d outer annular branch gas gas chambe and a gas pipe leadlng from sa1d valve and having branches opening in operative rela- Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D.
